Sharp boundaries between the standing and lying crop is the usual case in many newly-made, presumably authentic circles.
You'll see this typical kind of view, as you walk the sections of a complex formation.
The seed-heads in authentic formations are often neatly "steam-ironed" straight, and if you lift the straws, they crisply spring back into their lay-positions - whereas the seed-heads in the field immediately outside the formation are rounded, soft, and pliable.
Here the rows roundly turn a corner, forming the boundary to the next section.
48 shows a systematic diagonal slanting of overlapping rows; 49 a swerving overlapping pattern.
The weaving in different formations has different patterns, and this weaving repeats itself on large scale through an entire section. Notice how intricate it is: each bundle of straws lies both under and over other bundles, so there's no apparent linear time-sequence. Before it originally hits the ground, it's both covered by and covering parts of other falling bundles, indicating an extremely fast interacting order.
53 shows the lay into 4 directions in each of the ring's circles. The hill-mound, naturally part of the field before the formation, was incorporated as the symbol's center. Although this hill was covered with thistles, 54 shows the thistles-spiral which occured at its top.
When I visited this formation, it was the series of bare arcing lines you see in the first enlargment, which I couldn't make sense out of from my drawings at ground-level. A week later it changed to its later version. Sometimes a crop-circle evolves in even stranger ways.
This formation still felt powerful to me after the crop's harvest. The green growth in some formations is either from seeds which fall off the lying stalks as visitors tramp about, which then start to grow, or from weeds which get extra moisture and space when the tall surrounding grain lies flattened.
Even at a distance, it's rare to see a formation so clearly from the ground-level. In this case, the hill is a lot higher than the field.
A real beauty which it was not possible to walk up to and admire, due to the farmer's express wish that all crop-circle visitors keep out of his field.
Numerous bold, large yellow-and-black spiders had spun their homes across the tram-lines in one crop-circle field, and it took 5 minutes to move them and their cobwebs from the legs and clothes of the intruding visitor.
